DinRail 3-phase ULTRA

Meazon DinRail 3-phase ULTRA comes with three Split-Core Current Transformers which can measure up to 1700+ Amperes per Phase. Ideal for real time monitoring & control, equipped with build-in data logger, down to 1 second report interval over ZigBee and data uploading to the Cloud over Meazon Gateway. Meazon DinRail 3-Phase ULTRA is the proud winner of US Department of Energy Wireless submetering challenge.

Meazon circuit-level DinRail form-factor energy monitoring & control devices are so small that fit almost everywhere. Due to their optimal cost efficient design, they have a low TCO enabling the adoption of a larger number of metering points, driving much more detailed insight into energy efficiency opportunities.
